End of line insulation materials at reduced prices

Discontinued thicknesses and packaging changes mean certain PIR board sizes and foil-backed plasterboard lines are marked down to clear warehouse space. Stock is limited to what is physically on the shelf, so check availability before planning your project timeline.

View Offer

New customer welcome saving on your first order

First-time buyers get a money-off reduction when they set up an account and place their initial order. The discount applies across the full catalogue including thermal boards, acoustic rolls, and damp-proof membranes, with no minimum spend required.

View Offer

Volume pricing on bulk insulation purchases

Ordering pallet quantities of PIR boards, mineral wool, or plasterboard triggers tiered pricing that drops the unit cost as your quantity increases. The discounted rate shows up on the product page once you select higher pack sizes, so you can see the per-board saving before adding to basket.

NHS and key worker discount on insulation orders

Healthcare workers, emergency services staff, and military personnel can claim a reduced rate on insulation boards, rolls, and accessories. Verify your status through the checkout eligibility check and the saving applies automatically to your basket total.

View Offer

Free Tool with Selected Insulation Orders

Certain large insulation orders qualify for a complimentary installation tool or accessory bundled with the delivery. Look for products marked with the free gift badge when browsing - the offer applies automatically when the qualifying item is in your basket.

View Offer

Clearance Deals on End-of-Line Insulation

The clearance section features discontinued and overstocked insulation lines at significantly reduced prices. Stock changes frequently and once a line is gone it will not be restocked, so checking back regularly is worthwhile for bargain hunters.

Bulk Buy Savings on Insulation Packs

Ordering larger quantities brings the per-pack price down considerably. Multi-pack pallet deals on loft roll and mineral wool are priced lower than single-pack purchases, making them ideal for whole-house projects or contractors stocking up.
